FIELD OF THE INVENTION

The present disclosure provides new RNA-guided nuclease systems and engineered nickases for making rational, direct edits to nucleic acids in live cells.

INCORPORATION BY REFERENCE

Submitted with the present application is an electronically filed sequence listing via EFS-Web as an ASCII formatted sequence listing, entitled “INSC083US_seqlist_20210812”, created Aug. 12, 2021, and 359,000 bytes in size. The sequence listing is part of the specification filed herewith and is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

In the following discussion certain articles and methods will be described for background and introductory purposes. Nothing contained herein is to be construed as an “admission” of prior art. Applicant expressly reserves the right to demonstrate, where appropriate, that the methods referenced herein do not constitute prior art under the applicable statutory provisions.

The ability to make precise, targeted changes to the genome of living cells has been a long-standing goal in biomedical research and development. Recently, various nucleases have been identified that allow manipulation of gene sequence; hence, gene function. These nucleases include nucleic acid-guided nucleases. The range of target sequences that nucleic acid-guided nucleases can recognize, however, is constrained by the need for a specific PAM to be located near the desired target sequence. PAMs are short nucleotide sequences recognized by a gRNA/nuclease complex where this complex directs editing of the target sequence. The precise PAM sequence and PAM length requirements for different nucleic acid-guided nucleases vary; however, PAMs typically are 2-7 base-pair sequences adjacent or in proximity to the target sequence and, depending on the nuclease, can be 5′ or 3′ to the target sequence. Engineering nucleic acid-guided nucleases or mining for new nucleic acid-guided nucleases may provide nucleases with altered PAM preferences and/or altered activity or fidelity; all changes that may increase the versatility of a nucleic acid-guided nuclease for certain editing tasks.

There is thus a need in the art of nucleic acid-guided nuclease gene editing for novel nucleases with varied PAM preferences, varied activity in cells from different organisms such as mammals and/or altered enzyme fidelity. The novel MAD nucleases described herein satisfy this need.

Note that as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “an oligonucleotide” refers to one or more oligonucleotides. Terms such as “first,” “second,” “third,” etc., merely identify one of a number of portions, components, steps, operations, functions, and/or points of reference as disclosed herein, and likewise do not necessarily limit embodiments of the present disclosure to any particular configuration or orientation.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All publications mentioned herein are incorporated by reference for the purpose of describing and disclosing devices, methods and cell populations that may be used in connection with the presently described invention.

Where a range of values is provided, it is understood that each intervening value, between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges, and are also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either both of those included limits are also included in the invention.

In the following description, numerous specific details are set forth to provide a more thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without one or more of these specific details. In other instances, well-known features and procedures well known to those skilled in the art have not been described in order to avoid obscuring the invention.

The term “complementary” as used herein refers to Watson-Crick base pairing between nucleotides and specifically refers to nucleotides hydrogen bonded to one another with thymine or uracil residues linked to adenine residues by two hydrogen bonds and cytosine and guanine residues linked by three hydrogen bonds. In general, a nucleic acid includes a nucleotide sequence described as having a “percent complementarity” or “percent homology” to a specified second nucleotide sequence. For example, a nucleotide sequence may have 80%, 90%, or 100% complementarity to a specified second nucleotide sequence, indicating that 8 of 10, 9 of 10 or 10 of 10 nucleotides of a sequence are complementary to the specified second nucleotide sequence. For instance, the nucleotide sequence 3′-TCGA-5′ is 100% complementary to the nucleotide sequence 5′-AGCT-3′; and the nucleotide sequence 3′-TCGA-5′ is 100% complementary to a region of the nucleotide sequence 5′-TAGCTG-3′.

The term DNA “control sequences” refers collectively to promoter sequences, polyadenylation signals, transcription termination sequences, upstream regulatory domains, origins of replication, internal ribosome entry sites, nuclear localization sequences, enhancers, and the like, which collectively provide for the replication, transcription and translation of a coding sequence in a recipient cell. Not all of these types of control sequences need to be present so long as a selected coding sequence is capable of being replicated, transcribed and—for some components—translated in an appropriate host cell.

As used herein the term “donor DNA” or “donor nucleic acid” refers to nucleic acid that is designed to introduce a DNA sequence modification (insertion, deletion, substitution) into a locus by homologous recombination using nucleic acid-guided nucleases. For homology-directed repair, the donor DNA must have sufficient homology to the regions flanking the “cut site” or site to be edited in the genomic target sequence. The length of the homology arm(s) will depend on, e.g., the type and size of the modification being made. In many instances and preferably, the donor DNA will have two regions of sequence homology (e.g., two homology arms) to the genomic target locus. Preferably, an “insert” region or “DNA sequence modification” region—the nucleic acid modification that one desires to be introduced into a genome target locus in a cell—will be located between two regions of homology. The DNA sequence modification may change one or more bases of the target genomic DNA sequence at one specific site or multiple specific sites. A change may include changing 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 50, 75, 100, 150, 200, 300, 400, or 500 or more base pairs of the target sequence. A deletion or insertion may be a deletion or insertion of 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 40, 50, 75, 100, 150, 200, 300, 400, or 500 or more base pairs of the target sequence.

The terms “guide nucleic acid” or “guide RNA” or “gRNA” refer to a polynucleotide comprising 1) a guide sequence capable of hybridizing to a genomic target locus, and 2) a scaffold sequence capable of interacting or complexing with a nucleic acid-guided nuclease.

“Homology” or “identity” or “similarity” refers to sequence similarity between two peptides or, more often in the context of the present disclosure, between two nucleic acid molecules. The term “homologous region” or “homology arm” refers to a region on the donor DNA with a certain degree of homology with the target genomic DNA sequence. Homology can be determined by comparing a position in each sequence which may be aligned for purposes of comparison. When a position in the compared sequence is occupied by the same base or amino acid, then the molecules are homologous at that position. A degree of homology between sequences is a function of the number of matching or homologous positions shared by the sequences.

“Operably linked” refers to an arrangement of elements where the components so described are configured so as to perform their usual function. Thus, control sequences operably linked to a coding sequence are capable of effecting the transcription, and in some cases, the translation, of a coding sequence. The control sequences need not be contiguous with the coding sequence so long as they function to direct the expression of the coding sequence. Thus, for example, intervening untranslated yet transcribed sequences can be present between a promoter sequence and the coding sequence and the promoter sequence can still be considered “operably linked” to the coding sequence. In fact, such sequences need not reside on the same contiguous DNA molecule (i.e. chromosome) and may still have interactions resulting in altered regulation.

A “promoter” or “promoter sequence” is a DNA regulatory region capable of binding RNA polymerase and initiating transcription of a polynucleotide or polypeptide coding sequence such as messenger RNA, ribosomal RNA, small nuclear or nucleolar RNA, guide RNA, or any kind of RNA transcribed by any class of any RNA polymerase I, II or III. Promoters may be constitutive or inducible and, in some embodiments—particularly many embodiments in which selection is employed—the transcription of at least one component of the nucleic acid-guided nuclease editing system is under the control of an inducible promoter.

As used herein the term “selectable marker” refers to a gene introduced into a cell, which confers a trait suitable for artificial selection. General use selectable markers are well-known to those of ordinary skill in the art. Drug selectable markers such as ampicillin/carbenicillin, kanamycin, chloramphenicol, erythromycin, tetracycline, gentamicin, bleomycin, streptomycin, rhamnose, puromycin, hygromycin, blasticidin, and G418 may be employed. In other embodiments, selectable markers include, but are not limited to human nerve growth factor receptor (detected with a MAb, such as described in U.S. Pat. No. 6,365,373); truncated human growth factor receptor (detected with MAb); mutant human dihydrofolate reductase (DHFR; fluorescent MTX substrate available); secreted alkaline phosphatase (SEAP; fluorescent substrate available); human thymidylate synthase (TS; confers resistance to anti-cancer agent fluorodeoxyuridine); human glutathione S-transferase alpha (GSTA1; conjugates glutathione to the stem cell selective alkylator busulfan; chemoprotective selectable marker in CD34+cells); CD24 cell surface antigen in hematopoietic stem cells; human CAD gene to confer resistance to N-phosphonacetyl-L-aspartate (PALA); human multi-drug resistance-1 (MDR-1; P-glycoprotein surface protein selectable by increased drug resistance or enriched by FACS); human CD25 (IL-2α; detectable by Mab-FITC); Methylguanine-DNA methyltransferase (MGMT; selectable by carmustine); and Cytidine deaminase (CD; selectable by Ara-C). “Selective medium” as used herein refers to cell growth medium to which has been added a chemical compound or biological moiety that selects for or against selectable markers.

The terms “target genomic DNA sequence”, “target sequence”, or “genomic target locus” refer to any locus in vitro or in vivo, or in a nucleic acid (e.g., genome) of a cell or population of cells, in which a change of at least one nucleotide is desired using a nucleic acid-guided nuclease editing system. The target sequence can be a genomic locus or extrachromosomal locus.

A “vector” is any of a variety of nucleic acids that comprise a desired sequence or sequences to be delivered to and/or expressed in a cell. Vectors are typically composed of DNA, although RNA vectors are also available. Vectors include, but are not limited to, plasmids, fosmids, phagemids, virus genomes, synthetic chromosomes, and the like. As used herein, the phrase “engine vector” comprises a coding sequence for a nuclease to be used in the nucleic acid-guided nuclease systems and methods of the present disclosure. The engine vector may also comprise, in a bacterial system, the λ Red recombineering system or an equivalent thereto. Engine vectors also typically comprise a selectable marker. As used herein the phrase “editing vector” comprises a donor nucleic acid, optionally including an alteration to the target sequence that prevents nuclease binding at a PAM or spacer in the target sequence after editing has taken place, and a coding sequence for a gRNA. The editing vector may also comprise a selectable marker and/or a barcode. In some embodiments, the engine vector and editing vector may be combined; that is, the contents of the engine vector may be found on the editing vector. Further, the engine and editing vectors comprise control sequences operably linked to, e.g., the nuclease coding sequence, recombineering system coding sequences (if present), donor nucleic acid, guide nucleic acid, and selectable marker(s).

Editing in Nucleic Acid-Guided Nuclease Genome Systems

RNA-guided nucleases (RGNs) have rapidly become the foundational tools for genome engineering of prokaryotes and eukaryotes. Clustered Rapidly Interspaced Short Palindromic Repeats (CRISPR) systems are an adaptive immunity system which protect prokaryotes against mobile genetic elements (MGEs). RGNs are a major part of this defense system because they identify and destroy MGEs. RGNs can be repurposed for genome editing in various organisms by reprogramming the CRISPR RNA (crRNA) that guides the RGN to a specific target DNA. A number of different RGNs have been identified to date for various applications; however, there are various properties that make some RGNs more desirable than others for specific applications. RGNs can be used for creating specific double strand breaks (DSBs), specific nicks of one strand of DNA, or guide another moiety to a specific DNA sequence.

The ability of an RGN to specifically target any genomic sequence is perhaps the most desirable feature of RGNs; however, RGNs can only access their desired target if the target DNA also contains a short motif called PAM (protospacer adjacent motif) that is specific for every RGN. Type V RGNs such as MAD7, AsCas12a and LbCas12a tend to access DNA targets that contain YTTN/TTTN on the 5′ end whereas type II RGNs—such as the MADzymes disclosed herein—target DNA sequences containing a specific short motif on the 3′ end. An example well known in the art for a type II RGN is SpCas9 which requires an NGG on the 3′ end of the target DNA. Type II RGNs, unlike type V RGNS, require a transactivating RNA (tracrRNA) in addition to a crRNA for optimal function. Compared to type V RGNs, the type II RGNs create a double-strand break closer to the PAM sequence, which is highly desirable for precise genome editing applications.

A number of type II RGNs have been discovered so far; however, their use in widespread applications is limited by restrictive PAMs. For example, the PAM of SpCas9 occurs less frequently in AT-rich regions of the genome. New type II RGNs with new and less restrictive PAMs are beneficial for the field. Further, not all type II nucleases are active in multiple organisms. For example, a number of RGNs have been discussed in the scientific literature but only a few have been demonstrated to be active in vitro and fewer still are active in cells, particularly in mammalian cells. The present disclosure identifies multiple type II RGNs that have novel PAMs and are active in mammalian cells.

In performing nucleic acid-guided nuclease editing, the type II RGNs or MADzymes may be delivered to cells to be edited as a polypeptide; alternatively, a polynucleotide sequence encoding the MADzyme are transformed or transfected into the cells to be edited. The polynucleotide sequence encoding the MADzyme may be codon optimized for expression in particular cells, such as archaeal, prokaryotic or eukaryotic cells. Eukaryotic cells can be yeast, fungi, algae, plant, animal, or human cells. Eukaryotic cells may be those of or derived from a particular organism, such as a mammal, including but not limited to human, mouse, rat, rabbit, dog, or non-human mammals including non-human primates. The choice of the MADzyme to be employed depends on many factors, such as what type of edit is to be made in the target sequence and whether an appropriate PAM is located close to the desired target sequence. The MADzyme may be encoded by a DNA sequence on a vector (e.g., the engine vector) and be under the control of a constitutive or inducible promoter. In some embodiments, the sequence encoding the nuclease is under the control of an inducible promoter, and the inducible promoter may be separate from but the same as an inducible promoter controlling transcription of the guide nucleic acid; that is, a separate inducible promoter may drive the transcription of the nuclease and guide nucleic acid sequences but the two inducible promoters may be the same type of inducible promoter (e.g., both are pL promoters). Alternatively, the inducible promoter controlling expression of the nuclease may be different from the inducible promoter controlling transcription of the guide nucleic acid; that is, e.g., the nuclease may be under the control of the pBAD inducible promoter, and the guide nucleic acid may be under the control of the pL inducible promoter.

In general, a guide nucleic acid (e.g., gRNA) complexes with a compatible nucleic acid-guided nuclease and can then hybridize with a target sequence, thereby directing the nuclease to the target sequence. With the type II MADzymes described herein, the nucleic acid-guided nuclease editing system uses two separate guide nucleic acid components that combine and function as a guide nucleic acid; that is, a CRISPR RNA (crRNA) and a transactivating CRISPR RNA (tracrRNA). The gRNA may be encoded by a DNA sequence on a polynucleotide molecule such as a plasmid, linear construct, or the coding sequence may reside within an editing cassette and is under the control of a constitutive promoter, or, in some embodiments, an inducible promoter as described below.

A guide nucleic acid comprises a guide polynucleotide sequence having sufficient complementarity with a target sequence to hybridize with the target sequence and direct sequence-specific binding of a complexed nucleic acid-guided nuclease to the target sequence. The degree of complementarity between a guide sequence and the corresponding target sequence, when optimally aligned using a suitable alignment algorithm, is about or more than about 50%, 60%, 75%, 80%, 85%, 90%, 95%, 97.5%, 99%, or more. Optimal alignment may be determined with the use of any suitable algorithm for aligning sequences. In some embodiments, a guide sequence is about or more than about 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 35, 40, 45, 50, 75, or more nucleotides in length. In some embodiments, a guide sequence is less than about 75, 50, 45, 40, 35, 30, 25, 20 nucleotides in length. Preferably the guide sequence is 10-30 or 15-20 nucleotides long, or 15, 16, 17, 18, 19, or 20 nucleotides in length.

In the present methods and compositions, the components of the guide nucleic acid is provided as a sequence to be expressed from a plasmid or vector and comprises both the guide sequence and the scaffold sequence as a single transcript under the control of a promoter, and in some embodiments, an inducible promoter. In general, to generate an edit in a target sequence, the gRNA/nuclease complex binds to a target sequence as determined by the guide RNA, and the nuclease recognizes a protospacer adjacent motif PAM) sequence adjacent to the target sequence. The target sequence can be any polynucleotide endogenous or exogenous to a prokaryotic or eukaryotic cell, or in vitro. For example, the target sequence can be a polynucleotide residing in the nucleus of a eukaryotic cell. A target sequence can be a sequence encoding a gene product (e.g., a protein) or a non-coding sequence (e.g., a regulatory polynucleotide, an intron, a PAM, or “junk” DNA).

The guide nucleic acid may be part of an editing cassette that encodes the donor nucleic acid. Alternatively, the guide nucleic acid may not be part of the editing cassette and instead may be encoded on the engine or editing vector backbone. For example, a sequence coding for a guide nucleic acid can be assembled or inserted into a vector backbone first, followed by insertion of the donor nucleic acid in, e.g., the editing cassette. In other cases, the donor nucleic acid in, e.g., an editing cassette can be inserted or assembled into a vector backbone first, followed by insertion of the sequence coding for the guide nucleic acid. In yet other cases, the sequence encoding the guide nucleic acid and the donor nucleic acid (inserted, for example, in an editing cassette) are simultaneously but separately inserted or assembled into a vector. In yet other embodiments, the sequence encoding the guide nucleic acid and the sequence encoding the donor nucleic acid are both included in the editing cassette.

The target sequence is associated with a PAM, which is a short nucleotide sequence recognized by the gRNA/nuclease complex. The precise PAM sequence and length requirements for different nucleic acid-guided nucleases vary; however, PAMs typically are 2-7 base-pair sequences adjacent or in proximity to the target sequence and, depending on the nuclease, can be 5′ or 3′ to the target sequence. Engineering of the PAM-interacting domain of a nucleic acid-guided nuclease may allow for alteration of PAM specificity, improve fidelity, or decrease fidelity. In certain embodiments, the genome editing of a target sequence both introduces a desired DNA change to a target sequence, e.g., the genomic DNA of a cell, and removes, mutates, or renders inactive a proto-spacer mutation (PAM) region in the target sequence. Rendering the PAM at the target sequence inactive precludes additional editing of the cell genome at that target sequence, e.g., upon subsequent exposure to a nucleic acid-guided nuclease complexed with a synthetic guide nucleic acid in later rounds of editing. Thus, cells having the desired target sequence edit and an altered PAM can be selected using a nucleic acid-guided nuclease complexed with a synthetic guide nucleic acid complementary to the target sequence. Cells that did not undergo the first editing event will be cut rendering a double-stranded DNA break, and thus will not continue to be viable. The cells containing the desired target sequence edit and PAM alteration will not be cut, as these edited cells no longer contain the necessary PAM site and will continue to grow and propagate.

As mentioned previously, the range of target sequences that nucleic acid-guided nucleases can recognize is constrained by the need for a specific PAM to be located near the desired target sequence. As a result, it often can be difficult to target edits with the precision that is necessary for genome editing. It has been found that nucleases can recognize some PAMs very well (e.g., canonical PAMs), and other PAMs less well or poorly (e.g., non-canonical PAMs). Because the mined MAD nucleases disclosed herein may recognize different PAMs, the mined MAD nucleases increase the number of target sequences that can be targeted for editing; that is, mined MAD nucleases decrease the regions of “PAM deserts” in the genome. Thus, the mined MAD nucleases expand the scope of target sequences that may be edited by increasing the number (variety) of PAM sequences recognized. Moreover, cocktails of mined MAD nucleases may be delivered to cells such that target sequences adjacent to several different PAMs may be edited in a single editing run.

Another component of the nucleic acid-guided nuclease system is the donor nucleic acid. In some embodiments, the donor nucleic acid is on the same polynucleotide (e.g., editing vector or editing cassette) as the guide nucleic acid and may be (but not necessarily) under the control of the same promoter as the guide nucleic acid (e.g., a single promoter driving the transcription of both the guide nucleic acid and the donor nucleic acid). For cassettes of this type, see U.S. Pat. Nos. 10,240,167; 10,266,849; 9,982,278; 10,351,877; 10,364,442; 10,435,715; and 10,465,207. The donor nucleic acid is designed to serve as a template for homologous recombination with a target sequence nicked or cleaved by the nucleic acid-guided nuclease as a part of the gRNA/nuclease complex. A donor nucleic acid polynucleotide may be of any suitable length, such as about or more than about 20, 25, 50, 75, 100, 150, 200, 500, or 1000 nucleotides in length. In certain preferred aspects, the donor nucleic acid can be provided as an oligonucleotide of between 20-300 nucleotides, more preferably between 50-250 nucleotides. The donor nucleic acid comprises a region that is complementary to a portion of the target sequence (e.g., a homology arm). When optimally aligned, the donor nucleic acid overlaps with (is complementary to) the target sequence by, e.g., about 20, 25, 30, 35, 40, 50, 60, 70, 80, 90 or more nucleotides. In many embodiments, the donor nucleic acid comprises two homology arms (regions complementary to the target sequence) flanking the mutation or difference between the donor nucleic acid and the target template. The donor nucleic acid comprises at least one mutation or alteration compared to the target sequence, such as an insertion, deletion, modification, or any combination thereof compared to the target sequence.

Often the donor nucleic acid is provided as an editing cassette, which is inserted into a vector backbone where the vector backbone may comprise a promoter driving transcription of the gRNA and the coding sequence of the gRNA, or the vector backbone may comprise a promoter driving the transcription of the gRNA but not the gRNA itself. Moreover, there may be more than one, e.g., two, three, four, or more guide nucleic acid/donor nucleic acid cassettes inserted into an engine vector, where each guide nucleic acid is under the control of separate different promoters, separate like promoters, or where all guide nucleic acid/donor nucleic acid pairs are under the control of a single promoter. In some embodiments the promoter driving transcription of the gRNA and the donor nucleic acid (or driving more than one gRNA/donor nucleic acid pair) is an inducible promoter. Inducible editing is advantageous in that isolated cells can be grown for several to many cell doublings to establish colonies before editing is initiated, which increases the likelihood that cells with edits will survive, as the double-strand cuts caused by active editing are largely toxic to the cells. This toxicity results both in cell death in the edited colonies, as well as a lag in growth for the edited cells that do survive but must repair and recover following editing. However, once the edited cells have a chance to recover, the size of the colonies of the edited cells will eventually catch up to the size of the colonies of unedited cells. See, e.g., U.S. Pat. Nos. 10,533,152; 10,550,363; 10,532,324; 10,550,363; 10,633,626; 10,633,627; 10,647,958; 10,760,043; 10,723,995; 10,801,008; and 10,851,339. Further, a guide nucleic acid may be efficacious directing the edit of more than one donor nucleic acid in an editing cassette; e.g., if the desired edits are close to one another in a target sequence.

In addition to the donor nucleic acid, an editing cassette may comprise one or more primer sites. The primer sites can be used to amplify the editing cassette by using oligonucleotide primers; for example, if the primer sites flank one or more of the other components of the editing cassette.

In addition, the editing cassette may comprise a barcode. A barcode is a unique DNA sequence that corresponds to the donor DNA sequence such that the barcode can identify the edit made to the corresponding target sequence. The barcode typically comprises four or more nucleotides. In some embodiments, the editing cassettes comprise a collection of donor nucleic acids representing, e.g., gene-wide or genome-wide libraries of donor nucleic acids. The library of editing cassettes is cloned into vector backbones where, e.g., each different donor nucleic acid is associated with a different barcode.

Additionally, in some embodiments, an expression vector or cassette encoding components of the nucleic acid-guided nuclease system further encodes one or more nuclear localization sequences (NLSs), such as about or more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more NLSs. In some embodiments, the nuclease comprises NLSs at or near the amino-terminus of the MADzyme, NLSs at or near the carboxy-terminus of the MADzyme, or a combination.

The engine and editing vectors comprise control sequences operably linked to the component sequences to be transcribed. As stated above, the promoters driving transcription of one or more components of the mined MAD nuclease editing system may be inducible, and an inducible system is likely employed if selection is to be performed. A number of gene regulation control systems have been developed for the controlled expression of genes in plant, microbe, and animal cells, including mammalian cells, including the pL promoter (induced by heat inactivation of the CI857 repressor), the pBAD promoter (induced by the addition of arabinose to the cell growth medium), and the rhamnose inducible promoter (induced by the addition of rhamnose to the cell growth medium). Other systems include the tetracycline-controlled transcriptional activation system (Tet-On/Tet-Off, Clontech, Inc. (Palo Alto, Calif.); Bujard and Gossen, PNAS, 89(12):5547-5551 (1992)), the Lac Switch Inducible system (Wyborski et al., Environ Mol Mutagen, 28(4):447-58 (1996); DuCoeur et al., Strategies 5(3):70-72 (1992); U.S. Pat. No. 4,833,080), the ecdysone-inducible gene expression system (No et al., PNAS, 93(8):3346-3351 (1996)), the cumate gene-switch system (Mullick et al., BMC Biotechnology, 6:43 (2006)), and the tamoxifen-inducible gene expression (Zhang et al., Nucleic Acids Research, 24:543-548 (1996)) as well as others.

Typically, performing genome editing in live cells entails transforming cells with the components necessary to perform nucleic acid-guided nuclease editing. For example, the cells may be transformed simultaneously with separate engine and editing vectors; the cells may already be expressing the mined MAD nuclease (e.g., the cells may have already been transformed with an engine vector or the coding sequence for the mined MAD nuclease may be stably integrated into the cellular genome) such that only the editing vector needs to be transformed into the cells; or the cells may be transformed with a single vector comprising all components required to perform nucleic acid-guided nuclease genome editing.

A variety of delivery systems can be used to introduce (e.g., transform or transfect) nucleic acid-guided nuclease editing system components into a host cell. These delivery systems include the use of yeast systems, lipofection systems, microinjection systems, biolistic systems, virosomes, liposomes, immunoliposomes, polycations, lipid:nucleic acid conjugates, virions, artificial virions, viral vectors, electroporation, cell permeable peptides, nanoparticles, nanowires, exosomes. Alternatively, molecular trojan horse liposomes may be used to deliver nucleic acid-guided nuclease components across the blood brain barrier. Of particular interest is the use of electroporation, particularly flow-through electroporation (either as a stand-alone instrument or as a module in an automated multi-module system) as described in, e.g., U.S. Pat. Nos. 10,435,713; 10,443,074; 10,323,258; and 10,415,058.

After the cells are transformed with the components necessary to perform nucleic acid-guided nuclease editing, the cells are cultured under conditions that promote editing. For example, if constitutive promoters are used to drive transcription of the mined MAD nucleases and/or gRNA, the transformed cells need only be cultured in a typical culture medium under typical conditions (e.g., temperature, CO2 atmosphere, etc.) Alternatively, if editing is inducible—by, e.g., activating inducible promoters that control transcription of one or more of the components needed for nucleic acid-guided nuclease editing, such as, e.g., transcription of the gRNA, donor DNA, nuclease, or, in the case of bacteria, a recombineering system—the cells are subjected to inducing conditions.

EXAMPLES

The following examples are put forth so as to provide those of ordinary skill in the art with a complete disclosure and description of how to make and use the present invention, and are not intended to limit the scope of what the inventors regard as their invention, nor are they intended to represent or imply that the experiments below are all of or the only experiments performed. It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific aspects without departing from the spirit or scope of the invention as broadly described. The present aspects are, therefore, to be considered in all respects as illustrative and not restrictive.

Example 1: Exemplary Workflow Overview

The disclosed MADzyme Type II CRISPR enzymes were identified by the method depicted in FIG. 1. FIG. 1 shows an exemplary workflow for creating and for in vitro screening of MADzymes, including those in untapped clusters. In a first step, metagenome mining was performed to identify putative RGNs of interest based on, e.g., sequence (HMMER profile) and a search for CRISPR arrays. Once putative RGNs of interest were identified in silico, candidate pools were created and each MADzyme was identified by cluster, the tracrRNA was identified, and the sgRNA structure was predicted. Final candidates were identified, then the genes were synthesized. An in vitro depletion test was performed (see FIG. 2), where a synthetic target library was constructed in which to test target depletion for each of the candidate MADzymes. After target depletion, amplicons were produced for analysis for in vivo analysis. FIG. 2 depicts the in vitro depletion test in more detail.

Example 2: Metagenome Mining

The NCBI Metagenome database was used to search for novel, putative CRISPR nucleases using HMMER hidden Markov model searches. Hundreds of potential nucleases were identified. For each potential nuclease candidate, putative CRISPR arrays were identified and CRISPR repeat and anitirepeats were identified. Thirteen nucleases (FIG. 3) were chosen for in vitro validation and 11 active MADzymes were identified and assigned to clusters. There was less than 40% sequence identity between clusters. Cluster 59 shown in FIG. 4 presents two unique subclusters with distinct sgRNA architecture. Clusters 55-57 are shown in FIG. 5. These new MADzymes have diverse PAM preferences and distinct sgRNA structure. Cluster 141 (FIG. 6) is a distant cluster from 55, 56, 57 and 59 and shows diverse Cas protein structure and smaller-sized enzymes (e.g., approximately 200 amino acids shorter than the counterparts from the 55, 56, 57 and 59 clusters). Table 1 lists the identified MADzymes, including amino acid sequences, origin, and nucleic acid sequences of the CRISPR RNA and the trans-activating crispr RNA.

Example 3: Vector Cloning, MADZYME Library Construction and PCR

The MADzyme coding sequences were cloned into a pUC57 vector with T7-promoter sequence attached to the 5′-end of the coding sequence and a T7-terminator sequence attached to the 3′-end of the coding sequence.

First, Q5 Hot Start 2× master mix reagent (NEB, Ipswich, Mass.) was used to amplify the MADzyme sequences cloned in the pUC57 vector. The forward primer 5′-TTGGGTAACGCCAGGGTTTT [SEQ ID No. 172] and reverse primer 5′-TGTGTGGAATTGTGAGCGGA [SEQ ID No. 173] amplified the sequences flanking the MADzyme in the pUC57 vector including the T7-promoter and T7-terminator components at the 5′- and 3′-end of the MADzymes, respectively. 1 μM primers were used in a 10 μL PCR reaction using 3.3 μL boiled cell samples as templates in 96 well PCR plates. The PCR conditions shown in Table 2 were used:

STEP TEMPERATURE TIME DENATURATION 98° C. 30 SEC 30 CYCLES 98° C. 10 SEC 66° C. 30 SEC 72° C.  3 MIN FINAL EXTENSION 72° C.  2 MIN HOLD 12° C.

Example 4: gRNA Construction

Several functional gRNAs associated with each MADzyme was designed by truncating the 5′ region, the 3′ region and the repeat/anti-repeat duplex (see Table 3).

The target library was designed based on an assumption that the eight randomized NNNNNNNN [SEQ ID NO. 176] PAMs of these nucleases reside on the 3′ end of the target sequence (5′-CCAGTCAGTAATGTTACTGG [SEQ ID NO. 177]).

Example 5: In Vitro Transcription and Translation for Production of MAD Nucleases and gRNAs

The MADZYMEs were tested for activity by in vitro transcription and translation (txtl). Both the gRNA plasmid and nuclease plasmid were included in each txtl reaction. A PURExpress® In Vitro Protein Synthesis Kit (NEB, Ipswich, Mass.) was used to produce MADzymes from the PCR-amplified MADZYME library and also to produce the gRNA libraries. In each well in a 96-well plate, the reagents listed in Table 6 were mixed to start the production of MADzymes and gRNAs:

TABLE 6 REAGENTS VOLUME (μl) 1 SolA (NEB kit) 10 2 SolB (NEB kit) 7.5 3 PCR amplified gRNA 0.4 4 Murine RNase inhibitor (NEB) 0.5 5 Water 3.0 6 PCR amplified T7 MADZYMEs 3.6

A master mix with all reagents was mixed on ice with the exception of the PCR-amplified T7-MADZYMEs to cover enough 96-well plates for the assay. After 21 μL of the master mix was distributed in each well in 96 well plates, 4 μL of the mixture of PCR amplified MADZYMEs and gRNA under the control of T7 promoter was added. The 96-well plates were sealed and incubated for 4 hrs at 37° C. in a thermal cycler. The plates were kept at room temperature until the target pool was added to perform the target depletion reaction.

After 4 hours incubation to allow production of the MADzymes and gRNAs, 4 μL of the target library pool (10 ng/μL) was added to the 10 μL aliquots of in vitro transcription/translation reaction mixture and allowed to deplete for 30 min, 3 hrs or overnight at 37° C. and 48° C. The target depletion reaction mixtures were diluted into PCR-grade water that contains RNAse A incubated for 5 min at room temperature. Proteinase K was then added and the mixtures were incubated for 5 min at 55° C. RNAseA/Proteinase K treated samples were purified with DNA purification kits and the purified DNA samples were then amplified and sequenced. The PCR conditions are shown in Table 7:

Example 6: Measurement of Nicked Plasmid with Nickase RNP Complexes

Proteins were produced in vitro under a PURExpress® In Vitro Protein Synthesis Kit (NEB, Ipswich, Mass.). Guide RNAs that target the target plasmid were also produced under a T7 promoter in the same mixture. The MADzyme Nickase or Nuclease and guide complexes (RNP complex) formed as they were produced in the in vitro transcription and translation reagent. Supercoiled plasmid target was diluted into the digestion buffer, then the RNP complex was added to the same digestion buffer to initiate the plasmid digestion. After incubation at 37° C. to allow digestion of the plasmid, the resulting mixtures were treated with RNAase and Proteinase K, then the target plasmid was purified with a PCR cleanup kit, and run on TAE-agarose gel to observe the formation of nicked or double stand cut plasmid. The results are shown in FIG. 7. Table 8 lists the identified MADzyme nickases, including the variations from the nuclease sequence in Table 1 and the amino acid sequence.
